Coffee at Tate Modern

Just been to see the Exposed exhibition of street and other photography, at Tate Modern. A huge exhibition, but well worth seeing. My feet are a bit sore now, so restoring myself with a very nice cappuccino at the 4th floor cafe. This is the view.
National Portrait Gallery next on my one day cultural day out. But first making use of Tate Modern's free wi-fi to blip...
